Do you have more than one diagnoses?
Often, with ADHD/ADD, there is a co-diagnoses, like anxiety or depression. If you're also depressed, that would explain the lack of motivation.
I do not have that problem at all. In fact, I'm able to get quite a bit accomplished because I can now focus on what I'm doing, rather than being distracted by things all the time. That distraction used to keep me from getting anything done. So, now I'm doing much better.
You may want to talk to your doctor about this lack of motivation. I don't *think* it's due to the medication. You *may* have an underlying condition that hasn't yet been identified. But, please understand, I'm not a doctor. And only a doctor that you trust can really help you under these circumstances.
Best of luck. Let us know how it goes, ok? We care.
Peace!
